ROBERT J. MITCHELL, 0F MARION, OHIO.

LOCOMOTIVE Asia-ran.

Specification of Letters Patent.

Application filed August 14, 1909. Serial No. 512,787.

[0 all whom it may concern:

Beit known that 1, ROBERT J. MITCHELL, a citizen of the United States, residing at Marion, in the county of Marion and State of Ohio, have invented certain new and useful Improvements in Locomotive Ash-Pans, of which the following is a specification.

My invention relates to improvements'in locomotive ash-pans, and, more particularly, to fluid-operated ash-pan cleaning mechanism for use in connection with an ordinary locomotive and desi ned to be operated by a suitable operating ffillCl, such as steam, compressed air, or the like. 7

The primary object of the invention is to provide a generally improved device ofthis class which will be exceedingly sim le in' construction, cheap of manufacture, e cient in use, and much better adapted for its in-,

tended purpose than any other device of the same class with which I am acquainted.

With the above mentioned ends in view, the invention consists in the-novel construction, arrangement, and combination of parts, hereinafter described, illustrated in one of its embodiments in. the accompanying draw ings, and

articularly pointed out in the appended c aims.

Referring to the drawingsforming apart of. this specification, Figure 1 is a sideelevation 0 the improved device attached to the fire-box portion of a locomotive. Fig. 2,

a view, partly in horizontal section and partly in top plan, taken on line 2,-2, of Fig. 1. Fig. 3, a central sectional view of the fluid operatin cylinder. Fig.4, a cross sectional view 0 the same, takenthrough the line 4,4, of Fig. 1.

Similar numerals of reference desi 'nate like parts through all the figures o the drawmgs.

The improved ash-pan 1, maybe attached and secured beneath the grate-bars or gratings of the fire-box 2, in any suitable and convenient manner, and, in the present instance, is left open at'its forward end 1, as shown in the drawings.

The fluid cylinder 3, in the present instance, is mounted at the rear of the ash pan 1, and carried andmounted by means of a bracket 4;, secured to the rear of the firebox 2. The forward end of the cylinder 3, is secured to the-ash-pan 1, by means of I reciprocatin A scraper member or cross-head 7,. is slidably mounted in the ash-pan 1, and is adapted to impinge upon the bottom portion thereof inthe operation of clearing accumu-- lated ashes, and the like, as hereinafter described. The scraper member 7, terminates at its'sides -1, in upwardly and forwardly extending supporting arms 8, carrying a transversely disposed clinker cutting bar or member .9, carried just beneath the gratings of the fire-box in the reciprocatory movements of the scraper member for the purpose of impinging against such clinkers and t cinders as may extend down through'the grate bars and causing such clinkers' and einders to fall into the ash-pan below. The

. scraper member or cross head 7 is provided Patent-ed Jan; 18, 1910;

the ash-pan by at its'side's with guide members 10, extending into horizontal guide slots 11, in the side walls ofthe ash-pan and the adjacent inner sides \of the brace members 5.

The agitator bar 'or member 9, is preferably disposed at an angle to the plane of the grate-bars as shown and as a means for attached to the piston-rod 12, carriedby piston 13,.lzdapted toreciprocate in the cylin- -der3 by suitable operating fluid as now described. The operating Qfluid passes into the cylinder through the medium of a suitableconduit-pipe 14, leading to a horizontal inlet passage 15, of the wall of the cylinder. The

V the same, together with the scraper mem er or cross-head 7, the latter 1s.

valves (not shown) in conduit pipe 14, and

asa means for admitting the operating fluid into the cylinder for the purpose of recip-- rocating the piston, together with its attachments, inlet ports 16 are formed in the walls of the cylinder near each. end thereof and are adapted to be alternately thrown into and out of communication with the interior of the cylinder and the inlet passage 1 5 by means of the slide valve 17 provided -at its ends with downwardly extending flangeheads 17" adapted to be alternately engaged by upwardly extending flange heads 13 of the piston'as the latter is reciprocated. The spent operating fluid is adapted tobeejected through outlet ports 18, alternately opened and closed by the flange heads 17* of the slide valve 17 as the latter is reciprocated.

From the foregoing description taken in Connection with the accompanying drawings the operation and advantages of my invention will be readily understood.

Havin thus described one of the embodiments 0 my invention, what I claim and desire to secure by Letters Patent is 1. In a locomotive, the combination of a fire-box provided with grate-bars, an ashpandisposed beneath said grate-bars, and a scraper adapted to reciprocate in said ashpan and carrying a clinker cutting member ada ted to pass beneath the grate-bars of the re-box and remove the clinkers from the under sideof the same when the scraper is reciprocated.

2. In a locomotive, the combination jof a fire-box provided with grate-bars, an ashpan, a cylinder, a piston provided with a rod crrying a scraper, a clinker cutting member carried by said scraper and adapted-to pass beneath and remove the clinkers from the posed eneath said gratings,a fluid cylinder,

names a piston carrying a scraper slidable in said ash-pan, and a clinker cutting member arranged to pass beneath and remove the clinkers from the under side of the gratings when the scraper is reciprocated.

A. In a locomotive, a fire-box provided with gratings, an ash-pan disposed beneath said gratings, a cylinder, a piston provided with a rodcarrying a scraper in said ashpan, and arms on said scraper carrying a clinker cutting member disposed beneath said gratings and adapted to remove the clinkers from the underside of the same when the scraper is reciprocated.

5. In a locomotive, an ash-pan, open at its front and having its side walls provided with longitudinal guide slots, a cylinder, a piston carrying a scraper member provided with guides slidable in said guide slots, supporting arms carried by said scraper mem- "ber, a fire-box provided with gratings above said ash-pan, and a clinker cutting member carried by said supporting arms in front of said scraper member and adapted to pass beneath and remove the clinkers from said gratings when the scraper'is reciprocated.

In testimony. whereof I have afiixed my signature, in presence of two witnesses.
